Supersolid: Scientists turn light into a solid that flows like liquid for first time

Researchers have successfully turned light into a supersolid for the first time, marking a significant milestone in condensed matter physics. Using a semiconductor and laser, they created hybrid particles called polaritons that formed a supersolid state. This achievement builds on earlier work demonstrating light could behave like a fluid. The new light-based supersolid may be easier to work with than those made from atoms, potentially leading to new insights into quantum states of matter and applications in quantum technology.
